Two separate galaxies, NGC 4567 and
NGC 4568, form the Siamese Twins in the cluster of Virgo, and appear to
be interactive.L.S. Copeland was the first to refer to the galaxies as
the Siamese Twins. Some experts in the past have suggested that these
two galaxies happen to line up in a way that only gives the illusion that
they are interactive. These suggestions have been mostly overturned by
more recent discoveries, though there is some debate of whether the two
galaxies are actually interactive. The galaxies lie at a distance of about
42 million light-years away from Earth, with a linear size of about 73,000
light years.

As you can see in the photo above, both galaxies are spiral galaxies,
and appear to interact within the distant edges of each galaxy. In the
photo, the galaxies glow with a bright reddish yellow light. The galaxies
represent one of the many strange wonders of the outer universe.
